Abstract

On noie des fibres de carbone dans un revêtement en passant d'abord une couche d'un constituant époxy, par exemple, sur un sol ou sur un mur, puis en appliquant des feuilles de fibres de carbone fines, en enlevant éventuellement les fibres de carbone n'adhérant pas au revêtement après son séchage et en appliquant ensuite une ou plusieurs couches supérieures supplémentaires de revêtement pour noyer davantage les fibres de carbone. On obtient un revêtement de sol et/ou de mur électroconducteur et s'utilisant dans un environnement antistatique tel que des salles blanches, des salles d'opération, etc. Lesdits revêtements peuvent être à base d'uréthanes, époxys, alkydes, polyéthylènes, acryliques, vinyles, acétates de vinyle, esters, polyesters, sulfones, polysulfones, silicones, polysilicones ou autres, dans un base de solvant ou en suspension dans de l'eau. Les fibres de carbone préférées sont sous forme de "voiles" ou de "papier", dont la densité est généralement de 2,12 kg/0,84m2 environ (75 oz./square yard).
